According to an August study by Esticast Research & Consulting Market Research, the global commercial drone market may reach $3.6 billion by 2024. However, a new study forecasts an even larger bumper crop for just one of the many sub-sectors — agriculture, DroneLife.com reports.

The study, released this week by MarketInsightsReports, predicts the ag drone market will exceed the entire drone market value referenced in the Esticast report and do so two years earlier.

The report foresees a $4.2 billion value for the agricultural drone market by 2022 — representing a growth rate of 30 percent and beating Esticast’s overall prediction for the whole drone market by $600 million.

Although the marketing report is rather coy with the details – only offering a few tidbits in order to sell a $4,000 full report – it nevertheless touches on some of the key drone players in the growing ag sector such as PrecisionHawk, AeroVironment, Agribotix, AgEagle and DroneDeploy.
